Overview
Core area of research : Bioinformatics
Computational integrative analysis of microarray and RNA-seq datasets to identify and prioritize drug targets, validate targets, and discover potential compounds. Our approaches include drug repurposing, computer-aided drug design, and various ligand-based, structure-based, and docking/pharmacophore modeling strategies. Perform in vitro screening of lead compounds and existing drugs to identify those with specific activity against key targets, understand their mechanisms of action, and explore their biological effects—advancing the development of new therapies and biomedical innovations.
Training on the state of art advanced multi-omics techniques
The sessions of the training program were designed with comprehensive lectures focused on the theoretical knowledge of advanced multiomics and hands on training. The lecture sessions served as the intellectual backbone of the workshop, providing essential conceptual clarity before the corresponding hands-on sessions. Each lecture was carefully curated to connect foundational knowledge with emerging trends in multiomics, thereby fostering a holistic understanding of biomolecular research, diagnostics, and therapeutic innovations in cancer biology.
Prediction of T Cell And B Cell Epitopes For Akap A Cancer Testis Antigen By Computational And Experimental Analysis
Cancer testis antigens (CTAs) are aberrantly expressed in various cancers but not in normal tissues except in testis. This makes the CTAs represent potential candidate target for cancer immunotherapy. Akap3 and Akap4, members of the cancer testis antigen family, are primarily expressed during spermatogenesis in male germ cells and are not expressed in somatic cells. Because of their restricted expression, they are novel candidate molecules for immunotherapeutic targets. The immunoinformatics approach was utilized in this study to determine potential B and T cell epitopes for Akap3 and Akap4, which are significantly expressed in cancers.
